2 Claims.

My invention relates to improvements in tack pulling and collecting devices; and has for its general object to provide alight and easily operated implement which a large number or" tacks or nails can be quickly withdrawn and gathered up for further use.

The nature and scope oi the invention are clearly set forth in the following description, taken with the accompanying drawing, by which apreferred form of the invention is illustrated. The disclosure, however, is explanatory only, and I reserve the right to make changes in details of construction without departing from the principle of the invention or going beyond the broad and general meanings or" the terms in which the appended claims are expressed on said drawing:

Figure 1 is a side view of a. pulling and collecting device according to my invention.

Figure 2 is a vertical longitudinal section through the same.

Figure 3 is a horizontal section on the line 3-3 of Figure 2.

Figure 4 is a front view of an extractor member in the device showing the connection of said memher with the part for actuating the same.

The same numerals identify the same parts throughout. The numeral 1 indicates the body of the device, which has the form of a tray or a receptacle carrying at its front end an extractor member 2 which is worked by means of a lever or handle 3. The body has a roller 4 at the rear end and it is made so as to be open at the top and front. At the forward end the bottom of the receptacle 1 has several open-ended slots 5, the front extremities of the portions of the bottom of the receptacle between said slots being bent upward as shown at 6. The tacks or nails to be extracted are shown at '7 and these tacks, for example, may be used to hold any desired article that is to be secured in place, such as a piece of cloth or fur 8 that is stretched out to be dried or otherwise treated. The extractor member 2 is also slotted longitudinally; and as will be clear from Figure 2, when the device is moved along the cloth or fur 8, the tacks successively enter one or more of the slots 5 in the bottom of the receptacle 1 and the slots in the extractor member 2; which is held in depressed position so that it will readily engage the tacks. The slots of the member 2 are of less width than the heads of the tacks; and the tacks can be pulled out simply by depressing the handle 3. After extraction the tacks are dropped upon the bottom of th receptacle 1 towards the rear thereof and thus collected in a heap.

The extractor member 2 is made up of several longitudinal bars 9 spaced apart to provide the longitudinal slots above mentioned. This memher is attached to the lower end of the plunger 10 connected by a pivot pin 11 to the front end of the lever 3. The plunger 10 can move up and down in a bearing element 12 secured to projections 13 at the opposite sides of receptacle 1 by means of fastening device 14. The element 12 has a bore 15 through which the plunger 10 slides and carries the extension 16 projecting upward for connection with the lever B by means of a pivot pin 1'7. This lever may have two perforated lugs on its lower side between which the upper end of the extension is received, the pin 1'? passing through these lugs and the projection on the extension 16. A spring 18, attached at one end to the lever 3 between the extension 16 and plunger 10 and at its other end to a fixed point on extension 16, pulls the front end of the lever downward to hold the member 2 down in position to engage the tacks 7.

The lower end of the plunger 10 is recessed as shown at 19, Figure 4, and the bars 9 of the extractor member are attached to the parts 20 of the plunger 10 between the recesses 19. The recesses 19 have the form of grooves wide enough to pass the heads of the tacks 7. The slots in the member body between bars 9 are shown at 21.

I prefer to make the rear of the receptacle adjacent to the roller 4 relatively wide as shown at 22 to enlarge the capacity of the receptacle 1 so that a good many tacks can be withdrawn and deposited in the receptacle 1, from which they can be removed to be used if required.

In practice the device is used by moving it along a row of tacks so that the tacks pass into one or more of the slots 5 and one or more of the slots 21. The bars 9 of the member 2 slope upward somewhat in a rearward direction and the front ends must in any instance pass beneath the heads of the tacks 7, so that the tacks can be pulled out as the handle is depressed a number of times in succession. The tacks extracted by the member 2 are pushed along the slots 9 by the succeeding tacks that are pulled out until they reach the inner ends of the slots 5. At this point the tacks reach the bottom of the receptacle 1 and are moved still further until they clear the rear end of the extractor 2, whereupon the tacks fall upon the bottom of the wide portion 22 as indicated in Figures 2 and 3.

With this device a large number of tacks can be pulled in a short time and it is only necessary to move the device along a piece of cloth or fur or the like, to pull out a whole row of tacks or til several rows at once The tacks are extracted without being bent or deformed and without any risk of injuring the cloth or the fur; and after being collected in the receptacle 1 they can be used over if further need arises.

As appears from the foregoing description the device is quite simple, contains but few parts and is very certain in operation. The lower face of the bottom of the receptacle is made smooth and all liability of fur being damaged when the tacks are taken out is obviated.

The implement can of course be used to extract pins as Well as nails and tacks or in fact any similar fastening devices I claim:

1. A pulling device, comprising a receptacle having an open front end with slots in the bottom adjacent the front, the portions of the bottom between the slots being curved upward at their outer ends, a slotted extractor member above said slots, said number being inclined upward towards the rear end of said receptacle, a plunger attached to said extractor member, a bearing member mounted on the receptacle for said plunger, and a lever connected to said member and pivoted to said bearing member.

2. A pulling device comprising a movable body, a member mounted in said body to be lowered and raised, said member having longitudinal slots open at both ends to enable tacks to be extracted by engagement with the slots at one end thereof and then transmitted along said slots and delivered at the opposite ends.
